POWDER BOTTLE 0R CAVN CLOSRE.,

Applicatin led September 16, 1927. Serial No. 219,924.

This invention has reference to improvements in closures for bottles, cans or other receptacles adapted to contain powder or dry pulverulent or granular material.

This invention has for its principal object y to provide a novel construction and arrangement of perforate bottle cap or can top having a movable cover means for opening and closing the perforations at will, together with a novel means for so interrelating said cap and cover as to prevent sifting and leaking of the powder through the closure when the latter is in closed condition.

The invention has for a further object to provide a novel perforate cap and rotatable closing cover so constructed and combined that the parts are yieldably and yet securely held against accidental displacement fromV either the open or closed relation to which they may have been moved. v

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.'

The invention is clearly illustrated in the accompanying drawings, in which z- Figure 1 is a side elevation of thenovel closure of this invention provided in ther form of a bottle cap; Figure 2 is a topplan view of the same in closed condition; Figure 3 isa top plan view of the same in open condition; Figure 4 is an enlarged vertical cross section of the samein'closed condition taken on line 4 4 in Figure 2; Figure 5 is an enlarged vertical cross section of the same in open condition, taken on line 5 5 in Figure 3; and Figure 6 is a vertical cross section of the same showing the relation of the cover to the cap as the former is moving from open to closed position.

Similar characters of reference are employed in all of the hereinabove described views, to indicate corresponding parts.

Referring to said drawings, the reference character 7 indicates the neck port-ion of a bottle to contain powder vor the like, the same having at its extremity an annular enlargement Sto provide a shoulder 9.

The reference character 10 indicates a cap body adapted to extend over the mouth 11 of said bottle neck. Said cap body is preferably of concavo-convex shape and is provid- Y ed at its periphery with a depending skirt flange 12. The skirt liaugc 12 is of such diy ameter that it slidesover the enlargement 8 of thel bottle ncckso as to iit snugly around the same. Vhen the skirt flange 12 is thus engaged around said enlargement 8, the i'ree marginal port-ions `13 of said flange are inturned around and beneath the shoulder 9 of said enlargement, thereby securely intercoupling cap 10 in operative relation to the ,bottle neck. The cap member19 is provided `adjacent to its outer periphery and beyond said perforations 14with an exteriorly projected annular-header rib 16. i

vThe reference characterl-indicates a cover element. .This cover element-'is also of concaVo-convex form so as to snugly conform to and it over the cap member 10, and

said cover element is provided at its periphery with a depending annular flange 18 which overlicsV a portion of the skirt tiange 12 of said cap member. Saidcove'r element 17 is rotatably movable upon said cap member 10, and to vthis end a central pivoting l rivet 19 is passed through the cap member 10 and cover element 17 andheaded overon said t parts so as to retain the same against separation while neverthelessy permitting said cover element to rotatably slide upon said cap member. Said cover element is provided with a series of radially disposed periorations 20 corresponding in number and spacing to the perforations 14 oi said cap member so that at proper times said lpertorations 20 of the cover element may bebrought into Vbosses 21 into registration with the perforations 14 of the cap member, said bosses low bosses 21 results in the'prov1sion'-ofinl dividual cap-like closures foreach perforation and that consequentlythe tendency of ftliepowder'eontent, oflthe bottle tosift out of the-bottle and become'lodgcd between the i capanember 101 and `the. cover element'r 17 is 1B\, A ;reatlyA impeded ,and .substanti'allvY prevented. y Another advantage of the intrdovertailed relation ot` thegperforation` rims l5 ,withfthehollow bosses :21. lies in.. the r.fact

that l, accidental -'shifting movements l,of z the 20, coverelementupon the cap-membcn is .there- '.by.,prevented.so that. thecover element is- A.securely held in ,closed f position and yet. will readily .yield to, properly applied*l pressure utendingrtomanually rotate thesame to open 2li,` position. ,In ,i like mannenl Whenw the` cov- Ver elemental? is,disposed.imopenposition, iasillustratedinaFigure. .of y.the drawings, @they-perforation rims4 15 vvillv enterfintot-'he `perforations 2O ofthercover ielement andby .parts the.
